    Incineration technique is one of the effective methods for reducing solid wastes, but it makes secondary air pollutants such as SOx, NOx, HCl, and dioxins. Recently, dry type system is attractive in principle as compared with wet type or semi-dry type system at the point of maintenance and secondary pollutants. Therefore, to establish the most effective dry absorber for air pollutants removal system, we used laboratory scale parallel-flow dry absorber and scale up tests for this study. Laboratory scale dry absorber was designed of 1,280mm in height and 53mm in inner diameter. Reaction temperature was controlled to 190℃ by external electric heater. HCl (100~600ppm) gas was induced at the bottom of the reactor. Slaked lime [Ca(OH)₂] and/or activated carbon(AC) were injected into a parallel direction with gas flow. And, scale up tests were done at a pilot plant which consist of a system to treat 50m³/min actual gas flow out of 500m³/min exhaust gas from real incinerator with capacity of 70ton/day. The highest removal efficiency was obtained at stoichiometric ratio 3, temperature at 190℃, AC mixture ratio approximately 5% in laboratory scale parallel-flow dry absorber. And, base on those laboratory scale dry reactor test results, we performed several test in similar conditions. The highest removal efficiency was obtained at stoichiometric ratio 2~3, AC mixture ratio approximately 30% and re-circulation ratio 300% in pilot plant.
